YouTube is set to challenge established TV broadcasters by offering its own live channels.

The plans would enable YouTube’s millions of users to chat from their bedrooms, perform music or report on a breaking news story to a worldwide audience in real time.

A birthday party or wedding could be broadcast live to family and friends who are unable to attend. The truly committed could start a 24-hour ‘lifecast’ of their daily activities reminiscent of television’s Big Brother.

Does this mean lessons could be live cast as well? Implications for mobile phones?
